What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Preeclampsia (PE) is a major pregnancy complication characterized by hypertension and multiple end-organ dysfunctions; however, its detailed pathogenesis remains unclear. Extracellular vesicles (EVs) play diverse and critical roles in intercellular communication, and we have demonstrated interaction between EVs and vascular endothelial cells. Through serum proteomic analysis, we identified LIM and calponin homology domain-containing protein 1 (LIMCH1) as a PE-associated EV protein that is highly expressed in PE placentas, particularly in syncytiotrophoblasts, which release EVs into the maternal circulation. LIMCH1-enriched EVs (LIMCH1-EVs) increased endothelial permeability in vitro. Transcriptome analysis revealed that LIMCH1-EVs disrupted endothelial cell-cell junction assembly by suppressing the expression of the tight junction protein ZO-1. Furthermore, administration of LIMCH1-EVs promoted pulmonary vascular permeability in vivo. These findings suggest a role of LIMCH1-EVs in EV-associated vascular endothelial dysfunction, a central pathology of PE. In addition, this study provides insights into mechanisms that may contribute to PE-associated pulmonary edema, which have not yet been clarified.
